Record Everything with ATEM Mini Pro ISO

ATEM Mini Pro ISO from Blackmagic Design is a compact live-production switcher focused on multi-ISO recording and live-production features for DJs and live streamers. It is physically identical to the original ATEM Mini Pro while adding under-the-hood recording capabilities that expand post-event workflows. As a switcher, the unit lets operators rotate or switch between shots live during streaming or recording, enabling real-time program control. This introduction explains how its multi-ISO approach can be used in live DJ sets and streaming workflows.

The ATEM Mini Pro ISO records the program output and each HDMI input separately, producing full-quality standalone files for every source. Each HDMI input is captured as its own H.264 MP4 file, and audio is recorded independently as separate files for each input and microphone source. That ISO recording workflow allows re-editing after the live show by using the individual video ISOs to assemble a polished master or alternate mixes. For more engaging live streams, two or three camera angles—such as a side view and a top-down shot—are recommended to combine with the ISO files during post-production.

The ATEM Mini Pro ISO by Blackmagic Design enhances live production with its advanced recording capabilities. This device records the entire program output, ensuring that viewers see a consistent stream, while also capturing each HDMI input separately. This separation allows for each input to be saved as a standalone high-quality file. Specifically, each HDMI input is recorded as an H.264 MP4 file, a format that balances quality and efficient storage usage. Additionally, audio is managed independently, with separate recordings for each input and microphone source, which ensures precise synchronization during post-production.

This process allows for detailed re-editing post-event using the individual ISO files. The ATEM Mini Pro ISO’s functionality provides a flexible workflow, especially beneficial for creators who require detailed control over their multi-camera setups in environments such as DJ performances and live streaming events, where multiple angles enhance viewer engagement.

The ATEM Mini Pro ISO is physically identical to the original ATEM Mini Pro while adding recording capabilities under the hood. The unit retains the same external layout and controls as its predecessor and incorporates its multi-ISO recording features internally without altering the device’s physical design.

As a switcher, the ATEM Mini Pro ISO allows operators to rotate or switch between shots live during streaming or recording, enabling real-time selection of camera angles for the program output. This combination of an unchanged physical interface and integrated recording functionality supports live-production workflows used by DJs and live streamers.

The ATEM Mini Pro ISO’s ISO recording workflow captures the program output (what the audience sees) and each HDMI input as separate recordings. Each HDMI input is saved as its own H.264 MP4 file, and audio is recorded independently as separate files for each input and microphone source. Each recording is produced as a full-quality standalone file for its respective source. Those separate files form the individual video ISOs and isolated audio tracks that correspond to the program and each camera feed. The device functions as a switcher, allowing operators to rotate or switch between shots live during streaming or recording while the ISOs are being captured.

Because every source is recorded separately, the ISO recording workflow allows re-editing after the live show by using the individual video ISOs to assemble a polished master or alternate edits. For more engaging live streams, two or three camera angles are recommended to increase visual interest, with examples such as a side view and a top-down shot. The separation of program, source ISOs, and audio tracks provides distinct files that editors can combine or remaster in post-production. This arrangement preserves isolated feeds for each camera and microphone, supporting detailed editing decisions after the live performance. The workflow is intended to give creators flexibility in post-event editing by relying on the isolated video and audio files captured during the live session.

There is another ATEM Mini Pro, but the ATEM Mini Pro ISO takes everything good about the standard model and turns it into a powerful multi-ISO recorder.

The ATEM Mini Pro ISO’s big idea is simple, but powerful: Record everything!

Today, live-streamed DJ sets are no longer just a stopgap. They have become a legitimate path to real bookings, wider exposure, and sustainable DJ careers.

The ATEM Mini Pro ISO records both the program output and each HDMI input as separate files, with each HDMI input captured as an H.264 MP4 and audio recorded independently per input and microphone source. The unit is physically identical to the original ATEM Mini Pro while adding recording capabilities under the hood, and it functions as a live switcher that allows operators to rotate or switch between shots during streaming or recording.

The ISO recording workflow produces individual video ISOs and separate audio tracks that enable re-editing after a live show, allowing editors to assemble a polished master or alternate edits from the isolated source files.

For live DJ streams, the device’s capability to capture multiple isolated feeds supports setups using two or three camera angles, such as a side view and a top-down shot, to increase engagement and provide material for post-event editing.
